If you have surf you can go to driftveil city from the Pokemon center go right up and when you hit the lake go to the island in the middle and its right next to the lighthouse
One way is to talk to a guy on one of the piers in Castelia City. When he asks you if you chose Panpour, Pansage or Pansear, say "Panpour" and he will give you a water stone.
Normally, there would be about 2 or 3 of them during the course of the story.
Black: Cottonee. White: Petilil

You need a Shiny Stone to evolve into Cinccino.
After you beat the elite four, there's a zoarak out side victory road . Follow that zoarak and he will lead you to n , n gives you the black stone in pokemon black , and the white stone in pokemon white. Get the stone to dragonspiral tower and it will revive. Catch the legendary pokemon and then find kyurem in giant chasm. Before you beat the elite four, you will have to beat white/black kyurem after you beat it, there's the gene wedge on the floor.use that gene wedge to fuse reshiram/zekrom to kyurem to get black/white kyurem.
You need to use a water stone
Petilil will evolve with a sun stone, pansage with a leaf stone, panpour with a water stone, and pansear will evolve with a fire stone.
the light stone isn't in Pokemon white only the dark stone in white and the light stone in black
So far (although I have completed White not yet Black) all I know are Pansage (Leaf Stone), Pansear (Fire Stone) and Panpour (Water Stone). Sorry if this isn't as helpful as you hoped!
The Black Stone is on display at Nacrene City's museum.
Dusk stone: Lampent Fire stone: Pansear Leaf stone: Pansage Moon stone: Munna Shiny stone: Minccino Sun stone: Cottonee and Petilil Thunderstone: Eelektrik Water stone: Panpour

In Pokémon Black and White, a Water Stone will be given to you by a guy in Castelia City in the event of answering Panpour to his question. Other Water Stones will be found in Dust clouds that can be found in Mistralton Cave, Wellspring Cave, Chargestone Cave, Challenger's Cave, Twist Mountain, Giant Chasm and Victory Road.
You can only find a Magma Stone in Pokemon Black 2, White 2, Pokemon Diamond, Pearl, and Platinum. It is not available in Pokemon Black and White.
